In glance I get the same metrics, but I am not able to get a list of processes that are getting all the memory. I know that with glance I can print them, but I am not able to print all the pages (just the first one). Do you know another way to ge this info?

Re: HPUX 11.31 ia64 memory usage
ipcs -am ( active shared memory segments )
ps -efl |sort -rn +9 ( SZ of each proc, see ps man page for SZ definition )
Glance should give you a nice summary of memory use including:
Sys Mem
User Mem
Buf Cache
Free Mem

Re: HPUX 11.31 ia64 memory usage
When you print the first page in glance, then click "+" to print the next page.
If you click "?" sign, then you can get all the help related to glance.
Thanks,
Vivek

Re: HPUX 11.31 ia64 memory usage
you can use glance adviser mode like shown in examples at
/opt/perf/examples/adviser
it will give you a direct listing.

Re: HPUX 11.31 ia64 memory usage
Hi. I got the new version of kmeminfo from HP. Now we are seeing the ways to reduce the memory that uses the system.
I have looked at this thread, and I will probably try some of this:
http://h30499.www3.hp.com/t5/System-Administration/HPUX-11-31-the-quot-sys-mem-quot-is-too-high-it-eats-20-of-the/m-p/4749103#M388052
tool: kmeminfo 10.19 - libp4 9.543 - libhpux 1.372 - HP CONFIDENTIAL
unix: /stand/current/vmunix 11.31 64bit Tukwila on host "clase"
core: /dev/kmem live kernel!

time: Thu May 12 14:42:06 2011
nbpg: 4096 bytes
----------------------------------------------------------------------
Physical memory usage summary (in page/byte/percent):
Physical memory = 4168086 15.9g 100%
Free memory = 266047 1.0g 6%
User processes = 1303104 5.0g 31% details with -user
Detached SHMEM = 7 28.0k 0% details with -shmem

Kernel = 1872944 7.1g 45% kernel text and data
Dynamic Arenas = 1665989 6.4g 40% details with -arena
bc_bpdata_32K_a = 283296 1.1g 7%
misc region are = 133654 522.1m 3%

DMA32 free pool = 65256 254.9m 2%
Emergency pool = 8722 34.1m 0% system critical reserve
UAREA's = 16960 66.2m 0%

inode = 7616 29.8m 0%
bss = 6723 26.3m 0% vmunix bss section
Other tables = 3874 15.1m 0% details with -static
File Cache = 742623 2.8g 18% details with -ufc
For starting, I am thinking in setting vx_ninode to 131072 or less (now it has 0, automatic), set base_page_size to 16 (now it has 4) and set vx_ifree_timelag to -1 (now it has 0).
Any suggestion about it?

Re: HPUX 11.31 ia64 memory usage
you can see in the kmeminfo output
kmeminfo 10.19 - libp4 9.543 - libhpux 1.372 - HP CONFIDENTIAL
---------------
kmeminfo is a support tool which should be used only on hp request. To have an interpretation of the result, hp support will be the place to go.

Re: HPUX 11.31 ia64 memory usage
I modified the vx_ninode, as it had 0 value (default) and should be in a value of 131000 (aprox) for servers with a memory size of more than 3GB. And modified as well the vxfs_ifree_timelag to -1 in order to stop freeing inodes, as I have many FS.
I also reduced the value of filecache_max and filecache_min as they were not being used.
With this changes, I got 33% more of free memory. Before making these changes I asked HP about them, specially the vxfs_ifree_timelag.
Thanks for all your help.
